Linking the application is maddening.
So far I have tried
a space in the place of birth, no passport info and 2 then 3 applicants
actual place of birth, no passport info and 2 then 3 applicants
a space in the place of birth, passport info and 2 then 3 applicants
actual place of birth, passport info and 2 then 3 applicants
Still nothing. Annoyingly it's only giving me 4 tries before it locks me out for 24 hours instead of the 5 it says you have.
The only thing I can possibly think could be the problem is that I've put we're moving to Lunenburg in N.S. but there is an option for Lunenburg County. That will be what I'll try tomorrow.
Here's what worked for me (edited from OuIrish's advice):
1. Log in with GCKey account
2. Permanent Residence - Family Class (Spouses)
3. Application Number and Unique Client Identifier (UCI) - Insert application number and UCI from email
LEFT THIS BLANK: 4. City of Birth - Insert PA's City of Birth
LEFT THIS BLANK: 5. Country of Birth - Select PA's Country of birth
6. Passport Info - Insert Passport number, issuance and expiration info
7. Other Application Info - Fill out the other application info as per your application (Province, City and marital status) and put '2' as the number of
members in the application for sponsor + spouse (add +1 per dependent, if any)
8. Click on the 'Search for my application' tab
9. Then on 'Link my application' tab
